Josep,

I can't reproduce this, display (ImageMagick = 4:5.4.4.5-1woody1)
returns 0 when it exits for me. Are you using a different version? Is it
installed correctly or does it normally issue an error message when you
use it outside Octave?

A couple of possible workarounds could be to edit image.m, replacing

~  system (sprintf ("( %s || %s || %s && %s ) > /dev/null 2>&1 &",
~                   im_display, xv, xloadimage, rm));

with [*Untested*: Perhaps ppm file won't be removed!]

~  system (sprintf ("( %s || %s ) > /dev/null 2>&1 &", im_display, rm));


Alternatively, you could write a script to call display and exit with 0
and put it somewhere in your path before the real version, e.g.
[*Untested*, /usr/local/bin/display]
#!/bin/sh
/usr/bin/display $*
exit 0
